For developers, planning consultants, and land agents, this often means switching between several disconnected platforms just to answer a few fundamental questions. This fragmented workflow slows down planning due diligence, increases costs, and raises the risk of missing critical information.
In this guide, we break down the five essential land sourcing tools UK developers rely on, explain how they are traditionally used, and show how modern platforms are consolidating these functions into a single, streamlined workflow.
1. HM land registry: identifying who owns the land
HM Land Registry (HMLR) is the official body responsible for recording land and property ownership in England and Wales. It holds title records for land worth more than £8 trillion, making it one of the most critical tools for development site sourcing.
Before progressing any potential site, developers must confirm:
- Who owns the land
- Whether ownership is freehold or leasehold
- Any legal constraints affecting disposal or development
The traditional workflow
Traditionally, land sourcers access HMLR’s online portal on a site-by-site basis. Each search involves manually entering addresses, retrieving title numbers, and purchasing PDF title registers and plans.
For developers assessing multiple sites, this process quickly becomes time-consuming, repetitive, and costly.
How Searchland streamlines ownership research
Searchland integrates Land Registry ownership data directly into its map-based platform. Title boundaries and key ownership details are visible instantly for any parcel of land, without separate searches or document downloads.
Ownership data is refreshed every 24 hours, providing near real-time visibility. Searchland also includes a built-in mailshot tool, allowing users to send automated letter campaigns to landowners using verified Land Registry address data.
This removes friction between identifying land and initiating contact with owners.
2. Local authority planning registers: uncovering planning history
Every Local Planning Authority (LPA) in the UK is legally required to maintain a public register of planning applications. These records show whether development has been approved, refused, withdrawn, or remains pending.
Planning history is a cornerstone of site appraisal and planning due diligence, offering insight into policy interpretation, local constraints, and development precedent.
The traditional workflow
England alone has over 300 LPAs, each operating its own planning portal with different layouts and search functionality. Developers must manually search each council website, often address by address, to piece together planning history.
Older applications are frequently hard to find, and formats vary widely between authorities.
How Searchland aggregates planning data
Searchland aggregates more than 30 years of UK planning application data into a single, searchable national database.
Users can click on any site and instantly view:
- Approved, refused, withdrawn, and pending applications
- Full application histories for individual sites
- Nearby planning activity and comparable decisions
Planning data is updated every 24 hours and can be filtered by criteria such as:
- Applications within the last 10 years
- Approved residential developments
- Recent refusals on similar sites
- Pending applications nearby
As Neil Haynes from Strutt & Parker noted:
“Site assessments that took weeks now take one hour thanks to Searchland.”
3. Environment agency flood maps: assessing flood risk
Flood risk is a critical consideration for development feasibility. The Environment Agency’s Flood Map for Planning identifies whether a site falls within Flood Zone 1 (low risk), Flood Zone 2, or Flood Zone 3 (medium to high risk).
Sites within Flood Zones 2 or 3 typically require formal flood risk assessments and may face development restrictions.
The traditional workflow
Developers usually check flood risk separately via the Environment Agency’s website, manually entering locations and visually interpreting colour-coded maps. Surface water flood risk requires using a separate service entirely.
For large or multiple sites, this process is inefficient and prone to oversight.
How Searchland integrates flood risk data
Searchland includes official flood risk layers directly within its mapping platform. Users can toggle Flood Zone 2 and Flood Zone 3 overlays on and off while assessing sites.
Flood data is sourced from:
- The Environment Agency
- Natural Resources Wales
- SEPA (Scotland)
Surface water flooding maps were added in late 2023, allowing users to assess flood constraints across England, Wales, and Scotland without leaving the platform.
4. Natural England Magic Map: understanding environmental constraints
Natural England’s MAGIC (Multi-Agency Geographic Information for the Countryside) Map provides access to environmental and policy designations that can significantly affect development potential.
These include:
- Sites of Special Scientific Interest (SSSIs)
- National Parks and Areas of Outstanding Natural Beauty (AONBs)
- Green Belt boundaries
- Ancient woodland and conservation areas
The traditional workflow
The MAGIC website allows users to toggle multiple layers on an interactive map. However, cross-referencing environmental constraints alongside ownership and planning data requires switching between tools and repeated manual checks.
How Searchland consolidates constraint data
Searchland integrates environmental constraint layers directly into the same map used for ownership and planning analysis, including:
- SSSIs and Special Areas of Conservation
- National Parks and AONBs
- Green Belt boundaries
- Ancient woodland
- Agricultural land classifications
All data is sourced from official bodies such as Natural England and Historic England, allowing developers to identify constraints instantly during early-stage site assessment.
5. Ordnance survey and promap: accurate mapping and measurements
Accurate mapping underpins every stage of development site appraisal. Ordnance Survey (OS) provides the authoritative base mapping used by property professionals, while services such as Promap deliver OS data in a property-specific interface.
Mapping is essential for:
- Measuring site areas
- Understanding boundaries
- Assessing access and surrounding context
The traditional workflow
Most developers subscribe to standalone mapping services such as Promap, requiring a separate login and workflow to measure sites and create plans.
How Searchland leverages OS mapping
Searchland is powered by Ordnance Survey mapping, delivering the same level of accuracy within a single platform.
Users can:
- Measure site areas and distances directly on the map
- View boundaries alongside ownership and planning data
- Switch between mapping, satellite imagery, and street view
This enables fast, desk-based site appraisal without relying on multiple tools.
Bonus: Companies house integration for ownership insights
When land is owned by a company rather than an individual, developers often need Companies House data to understand ownership structures and identify decision-makers.
Searchland automatically pulls Companies House information for company-owned sites, displaying:
- Company registration details
- Correspondence addresses
- Director information
This data can be used directly for outreach, with company addresses auto-populated into letter templates.
All-in-one efficiency for land sourcing
Land Registry, planning registers, flood maps, MAGIC Map, OS mapping, and Companies House have long been the foundation of UK site sourcing. However, using each tool separately creates inefficiencies, duplication, and risk.
Searchland consolidates these essential land sourcing tools into a single, map-based platform. By layering ownership, planning history, environmental constraints, flood risk, and mapping together, developers can assess sites faster and with greater confidence.
Instead of juggling multiple subscriptions and council websites, UK land professionals can answer five critical questions in one place:
- Who owns the land?
- What is the planning history?
- Are there flood or environmental constraints?
- What is the site area and context?
- Who are the decision-makers behind the ownership?
